Question

I have an element that looks something like this:

 ___
|  X|
 ‾‾‾ 

So essentially a tiny box with a button to close it.

I have also applied CSS to the element, so that when hovered, it will turn to something like this:

 ___________________
|                  X|
 ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾

Simply put, it’ll just become wider.

Now. what I want to do is that whenever the user hovers over the close button (X), the box will not change its size.
But when the user hovers on anywhere else on the box, it would behave as suggested.

Is this possible with pure CSS?

EDIT: Sorry that I added this late, but the answers should be based around this example: http://jsfiddle.net/fpY34

Answer 1

Using the markup you have, I have no clue how to do it without fixed widths, and absolute nastiness. But here’s me giving my all! http://jsfiddle.net/fpY34/15/

<div id='outer'>
    <div id='notOuter'>
        <div id='content'>
            <div id='img'>
            </div>
            <div id='label'>
                Text example
            </div>
            <div id='closeButton'>
                X
            </div>
        </div>
    </div>
</div>​

and the beauty:

#outer { height: 30px; }
#notOuter {}
#content { float: left; position: relative; }
#closeButton { background: #0f0; position: absolute; top: 0; left: 30px; width: 30px; height: 30px;} 
#img { background: #f0f; width: 30px; height: 30px; position: absolute; left: 0; top: 0; }
#label { display: none; position: absolute; left: 0; top: 0; width: 60px; height: 30px; background: #f00; }
#img:hover { width: 60px; z-index: 10; }
#img:hover + #label,
#label:hover { display: block; z-index: 20; }
#img:hover ~ #closeButton,
#label:hover + #closeButton { left: 60px; }
